Liquid Dividing Device, Shell Design

Dividing section of the head has a strip-silvered vacuum jacket. Jacket is equipped with internal bellows to allow for expansion due to temperature differential. Jacket is evacuated to 5 x 10-8 mm Hg. Takeoff is controlled by means of a swinging bucket with a glass-enclosed iron core, energized by an external solenoid. In normal position reflux is returned to the column; when energized, condensate is directed to the take-off. Supplied with AC magnet, o-ring ball joint connecting tube, thermocouple, and clamps.
